. and today sadness as bodies of four americans returned home after being killed in beng hasy -- benghazi, lickia. >> there has bain difficult week for the state department and for our country. we've seen the heavy assault on our post in benghazi that took the lives of those brave men. we've seen rage and violence directed at american embassies over an awful internet video that we had nothing to do with. it is hard for the american people to make sense of that because it is senseless. the people of egypt, libya, yemen, and tunisia did not trade the tyranny of a dictator for the tyranny of a mob. gwen: but the protests have spread as this google map shows. throughout the middle east and beyond. you can look and see -- it's pakistan, in london, it's everywhere all over the region and beyond. what happened in benghazi was tragic, but is this something that had been building for some time, david? or was this just the spark? >> gwen, i think it was the flip side of these revolutions that we all watched with sauch maysment and such enthusiasm in some cases in january and february of last year.
